Solve the equation. –x 8 3x = x – 6 x = –18 x = –14 x = 2 x = 4
LenKa [72]

The value of the variable x in the equation –x + 8 + 3x = x – 6 is - 14.

<h3>How to find variable in an equation?</h3>

The variables of an equation can be found as follows:

–x + 8 + 3x = x – 6

The variable in the equation is x.

Therefore,

–x + 8 + 3x = x – 6

combine like terms on the left side

-x + 3x + 8 = x - 6

2x + 8 = x - 6

subtract x form both sides of the equation

2x - x + 8 = - 6

x + 8 = -6

subtract 8 from both sides

x = -6 - 8

x = - 14

If lim x-&gt; 4 f(x)=5 lim x-&gt; 4 f g(x)=0 and lim x-&gt; 4 f h(x)=-2, then find lim (fg)(x)
Lyrx [107]

Answer:

0

Step-by-step explanation:

Assuming the problem is:

"lim x-> 4 f(x)=5 lim x-> 4 g(x)=0 and lim x-> 4 h(x)=-2, then find lim x->4 (fg)(x)"

lim x->4 (fg)(x)

Since we know the limits of f and g at x=4 exist we can write the limit as:

lim x->4 f(x) lim x->4 g(x) (since fg(x) means f times g of x.)

What is the reason for each strip on the solution of the equation?
Pani-rosa [81]

Step 1: Given

Step 2:  Distributive Property

Step 3: Addition Property of  Equality

Step 4: Division Property of  Equality

Step-by-step explanation:

We need to match the reason with the correct step in the equation.

Equation:

Given:

2x = -4(x-3)

Applying Distributive property a(b+c)=ab+ac

2x=-4x+12

Now, Applying addition property of equality:

Adding +4x on both sides

2x+4x=-4x+12+4x\\6x=12

Now, Applying Division property of Equality:

Divide both sides by 6:

\frac{6x}{6}=\frac{12}{6}\\x=2

So, Answer will be:

Step 1: Given

Step 2:  Distributive Property

Step 3: Addition Property of  Equality

Step 4: Division Property of  Equality
